有機發光二極體顯示面板觸控結構Organic light emitting diode display panel touch structure

本創作係關於一種具有觸控板的顯示螢幕之結構，尤指一種有機發光二極體顯示面板觸控結構。The present invention relates to a display screen having a touch panel, and more particularly to an organic light emitting diode display panel touch structure.

近年來平面顯示器產業迅速發展，許多產品也被相繼提出，以追求重量更輕、厚度更薄、體積更小與更加細緻的影像品質。並且發展出了數種的平面顯示器來取代傳統的陰極射線管顯示器(CRT)。圖1係習知平面顯示器種類的示意圖，如圖1所示，習知平面顯示器包括了液晶顯示器(Liquid Crystal Display,LCD)、電漿顯示器(Plasma Display Panel,PDP)、有機發光二極體(Organic Light Emitting Diode,OLED)顯示器、場發射顯示器(Field Emission Display,FED)、及真空螢光顯示器(Vacuum Fluorescence Display,VFD)。In recent years, the flat panel display industry has developed rapidly, and many products have been proposed in order to pursue lighter weight, thinner thickness, smaller size and more detailed image quality. And several flat panel displays have been developed to replace the traditional cathode ray tube display (CRT). 1 is a schematic diagram of a conventional flat panel display. As shown in FIG. 1, a conventional flat panel display includes a liquid crystal display (LCD), a plasma display panel (PDP), and an organic light emitting diode ( Organic Light Emitting Diode (OLED) display, Field Emission Display (FED), and Vacuum Fluorescence Display (VFD).

在眾多種類的平面顯示器中，有機發光二極體顯示技術(OLED)是極具潛力的新興平面顯示技術。OLED是1987年由美國柯達(Eastman Kodak Co.)公司所發表。其具有厚度薄、重量輕、自發光、低驅動電壓、高效率、高對比、高色彩飽和度、反應速度快、可撓曲等特色，因此被視為 繼TFT-LCD之後，相當被看好的顯示技術。近年來行動通訊、數位產品與數位電視對高畫質全彩平面顯示器的需求急速增加。OLED顯示器不但具有LCD的輕薄、省電與全彩顯示的優點，更具有比LCD更好的廣視角、主動發光、反應速度快的特性。Among many types of flat panel displays, organic light-emitting diode display technology (OLED) is an emerging new flat display technology. OLED was published in 1987 by Eastman Kodak Co.. It has the characteristics of thin thickness, light weight, self-illumination, low driving voltage, high efficiency, high contrast, high color saturation, fast response, flexibility, etc. Following TFT-LCD, it is quite a good display technology. In recent years, the demand for high-quality full-color flat-panel displays in mobile communications, digital products and digital televisions has increased rapidly. The OLED display not only has the advantages of thin, power-saving and full-color display of the LCD, but also has a wider viewing angle, active illumination, and faster response than the LCD.

圖2係一習知有機發光二極體(Organic Light Emitting Diode,OLED)顯示器基本構造之示意圖，該有機發光二極體(OLED)顯示器200包含一陰極層210、一有機發光二極體層220、一陽極層230、一薄膜電晶體層250、一反射層260、一下基板270、及一上基板280等結構層，其中該有機發光二極體層220更包含一電洞傳輸子層(hole transporting layer,HTL)221、一發光層(emitting layer)223、及一電子傳輸子層(electron transporting layer,HTL)225。2 is a schematic diagram of a basic structure of a conventional organic light emitting diode (OLED) display. The organic light emitting diode (OLED) display 200 includes a cathode layer 210 and an organic light emitting diode layer 220. a structural layer such as an anode layer 230, a thin film transistor layer 250, a reflective layer 260, a lower substrate 270, and an upper substrate 280, wherein the organic light emitting diode layer 220 further includes a hole transport layer , HTL) 221, an emission layer 223, and an electron transporting layer (HTL) 225.

有機發光二極體之發光原理是藉著外加電場的作用，使電子、電洞分別從陰極層210、陽極層230注入，電洞經過電洞傳輸子層221、電子通過電子傳輸子層225之後，進入具有螢光特性的發光層223。接著在內部結合產生激發光子，激發光子隨即將能量釋放並回到基態(Ground state)，被釋出的能量會根據不同的發光材料產生不同顏色的光，而造就了OLED的發光現象。The principle of illuminating the organic light-emitting diode is to inject electrons and holes from the cathode layer 210 and the anode layer 230 respectively by the action of an applied electric field, and the holes pass through the hole transport sub-layer 221, and the electrons pass through the electron transport sub-layer 225. The light-emitting layer 223 having a fluorescent property is entered. Then, the internal excitation generates photons, and the excited photons are released and returned to the ground state. The released energy generates different colors of light according to different luminescent materials, which creates the luminescence phenomenon of the OLED.

習知的有機發光二極體(Organic Light Emitting Diode,OLED)顯示器200在上基板280下方有一陰極層210，該陰極層210可隔絕來自上基板280上方的雜訊，並接收該陽極層230之畫素電極的電流，以控制發光層223的發光。A conventional Organic Light Emitting Diode (OLED) display 200 has a cathode layer 210 under the upper substrate 280. The cathode layer 210 can isolate noise from the upper substrate 280 and receive the anode layer 230. The current of the pixel electrode controls the light emission of the light-emitting layer 223.

習知之觸控式平面顯示器係將觸控面板與平面顯示器直接進行上下之疊合，因為疊合之觸控面板為透明之面板，因而影像可以穿透疊合在上之觸控面板顯示影像，再藉由觸控面板作為輸入之媒介或介面。然而這種習知之技藝，因為於疊合時，必須增加一個觸控面板之完整重量，使得平面顯示器重量大幅地增加，不符合現時市場對於顯示器輕薄短小之要求。而直接疊合觸控面板以及平面顯示器時，在厚度上，增加了觸控面板本身之厚度，降低了光線的穿透率，增加反射率與霧度，使螢幕顯示的品質大打折扣。The touch-sensitive flat panel display directly overlaps the touch panel and the flat display, because the laminated touch panel is a transparent panel, so that the image can penetrate the display image of the touch panel stacked thereon. Then use the touch panel as the medium or interface for input. However, this conventional technique is required to increase the total weight of a touch panel when superimposing, so that the weight of the flat display is greatly increased, which does not meet the requirements of the current market for the lightness and thinness of the display. When the touch panel and the flat display are directly stacked, the thickness of the touch panel itself is increased in thickness, the light transmittance is reduced, the reflectance and the haze are increased, and the quality of the screen display is greatly reduced.

針對前述之缺點，觸控式平面顯示器改採嵌入式觸控技術。嵌入式觸控技術目前主要的發展方向主要為In-Cell技術。In-Cell Touch技術則是將觸控元件整合於顯示面板之內，使得顯示面板本身就具備觸控功能，因此不需要另外進行與觸控面板貼合或是組裝的製程，這樣技術通常都是由TFT LCD面板廠開發。In response to the aforementioned shortcomings, the touch panel display adopts an embedded touch technology. The main development direction of embedded touch technology is mainly In-Cell technology. In-Cell Touch technology integrates the touch components into the display panel, so that the display panel itself has a touch function, so there is no need to separately attach or assemble the touch panel, so the technology is usually Developed by TFT LCD panel factory.

然而由於有機發光二極體顯示器200的該陰極層210，此會使得觸控訊號被該陰極層210遮罩，而導致In-Cell嵌入式觸控技術難以應用在有機發光二極體(Organic Light Emitting Diode,OLED)顯示器200上。因此，習知有機發光二極體液晶顯示面板結構仍有改善的空間。However, due to the cathode layer 210 of the organic light emitting diode display 200, the touch signal is masked by the cathode layer 210, which makes the In-Cell embedded touch technology difficult to apply to the organic light emitting diode (Organic Light). Emitting Diode, OLED) display 200. Therefore, there is still room for improvement in the structure of the conventional organic light emitting diode liquid crystal display panel.

本創作之主要目的係在提供一種有機發光二極 體顯示面板觸控結構，可讓In-Cell嵌入式觸控技術應用在有機發光二極體顯示面板上，同時可大幅節省材料成本及加工成本，無須改變製程，即可使有機發光二極體顯示面板有觸控功能。The main purpose of this creation is to provide an organic light-emitting diode The body display panel touch structure enables the In-Cell embedded touch technology to be applied to the organic light emitting diode display panel, and at the same time, the material cost and the processing cost can be greatly saved, and the organic light emitting diode can be made without changing the process. The display panel has a touch function.

FIG. 5 is a schematic illustration of the cathode layer 350 and the thin film transistor layer 340 of the present invention. Since the cathode layer 350 is formed of a metal conductive material, the gate driving line 203, the source driving line 204, and the pixel transistor 341 of the thin film transistor layer 340 can be seen in FIG.

由圖4及圖5所示可知，該陰極層350位於該第一基板310與該有機發光二極體層(OLED)330之間，該陰極層350具有複數個多邊形通孔181，該複數個多邊形通孔181設置位置係相對於該薄膜電晶體層340的閘極驅動線203及源極驅動線204。As shown in FIG. 4 and FIG. 5, the cathode layer 350 is located between the first substrate 310 and the organic light emitting diode layer (OLED) 330. The cathode layer 350 has a plurality of polygonal through holes 181, and the plurality of polygons The via 181 is disposed at a position relative to the gate drive line 203 and the source drive line 204 of the thin film transistor layer 340.

The two polygonal through holes 181 of the plurality of polygonal through holes 181 on the cathode layer 350 are not connected.

Through hole 181. Fig. 7 is a schematic view showing still another embodiment of the present invention, which differs from Fig. 6 in that the polygonal through hole 181 is an octagonal shape.
